Frequently Asked Questions about Carbon Monoxide

Carbon monoxide is an odorless and colorless gas that is harmful. When CO enters the body, it prevents the blood from bringing oxygen to cells, tissues and organs. Because it is impossible to see, taste or smell, CO can kill you before you are aware it is in your home.

The initial symptoms of low to moderate CO poisoning are similar to the flu (but without the fever). They include:

Headache

Fatigue

Shortness of breath

Nausea

Dizziness

High level CO poisoning has more severe symptoms, including:

Mental confusion

Vomiting

Loss of muscular coordination

Loss of consciousness

Ultimately death

The amount of CO you’re exposed to influences the recovery and the damage done. If you or your family experience any of the above symptoms and believe you may have been exposed to CO, you should leave the house immediately and seek urgent medical advice from your doctor.

If you think you are experiencing any of the symptoms of CO poisoning, get fresh air immediately. Leave your home and call 911 to report your symptoms and the possibility of CO exposure. If you do not have a cell phone to make the call, ask a neighbor if you can use their phone. You could lose consciousness and die if you stay in the home. It is also important to contact a doctor immediately or go to the emergency room for a proper diagnosis. Tell your doctor that you suspect CO poisoning is causing your symptoms. Quick medical attention is important if you are experiencing any symptoms of CO poisoning. If the doctor confirms CO poisoning, make sure a qualified service person checks the appliances for proper operation before using them.
